［Objective］ Research hotspots and developmental trends of grazing impacts on plant-soil interactions in grassland ecosystems were systematically evaluated to provide a basis for management of grassland ecology. ［Methods］ Using R language， CiteSpace， and VOSviewer software， 10，809 articles from the Web of Science and China National Knowledge Infrastructure databases published from 2000 to 2023 were analyzed. ［Results］ The number of publications in this field showed an increasing trend， both domestically and internationally. Research has mainly focused on the effects of grazing management on vegetation community characteristics and soil cycling in climate-sensitive grassland areas. The research perspective has gradually shifted from traditional plant community-population-individual ecological investigations of grazing intensity and climate change impacts to ecosystem reproduction， renewal， and carbon balance characteristics， and ultimately to optimizing management models for fragile ecosystems based on multifactor interactions. This transition marks the evolution of grassland ecology research from macro-to micro-scale studies ［Conclusion］ Future research should incorporate advanced methods from related fields to enhance our understanding of the complex mechanisms of cross-scale and multimode interactions in ecosystems and combine small-scale experimental results with regional and global ecological models. Emphasis should be placed on the multidimensional， multiscale， and multifactor impacts on the linkage between aboveground and belowground ecological processes to promote optimization of ecosystem management and conservation strategies.
